The Celsius Scale
The Rankine scale is one of the temperature scales used when an absolute temperature scale is needed. The Rankine scale is useful in calcluations of oil or gas present in an oil or gas reservoir (one of the factors in the equations is the ratio of standard temperature to formation temperature; generally add 460 to the temperature in degrees Fahrenheit to obtain degrees Rankine).
Formulas for conversion are: R = F + 459.67 F = R - 459.67
The Fahrenheit scale is not absolute and also is obsolete.The absolute scale is Kelvin.
37 degrees Celsius = 558.27 degrees Rankine.
There are four units for temperature: Celsius, Kelvin, Fahrenheit, and Rankine. The Kelvin scale is the same as the Celsius scale, just with the zero point being absolute zero. The Rankine scale is the same thing for the Fahrenheit scale. ■
the four termometric scales are: -Celsius -Fahrenheit -Kelvin -Rankine
100 degrees on the Celsius scale, 212 degrees on the Fahrenheit scale, 373 Kelvins, and 671 degrees (rounded) on the Rankine scale are all the same temperature.
It is an absolute measurement scale of temperature. 0K is absolute zero there are no negative units on the scale (degrees centigrade [celsius] + 273 = degrees Kelvin). This also is the case on the Rankine temperature scale (degrees fahrenheit +459.69 = degrees Rankine)
To convert from degrees Celsius into degrees Rankine, add 273.15, multiply by 9, and divide by 5. For example, 0 degrees Celsius is equal to (0 + 273.15) = 273.15 x 9 = 2458.35 / 5 = 491.67 degrees Rankine. R = 9/5 (C + 273.15) For every additional degree Celsius, the difference between Rankine and Celsius increases by 9 / 5 = 1.8 degrees - the same amount as it increases for x+1 degrees Fahrenheit. Here is a small table: 0 degrees C = 491.67 Rankine. 1 degree C = 493.47 Rankine. 2 degrees C = 495.27 Rankine. Similarly, for every increase of one degree Fahrenheit, the number of degrees Rankine increases by 1. For example: 32 Fahrenheit = 491.67 Rankine 33 Fahrenheit = 492.67 Rankine. To convert Celsius to Rankine, first convert Celsius to Kelvin by adding 273.15, then multiply by 9/5 or by 1.8 to get the Rankine temperature. R = 9/5 (C + 273.15) *Rankine is the Fahrenheit temperature scale re-adjusted to start at absolute zero, so it is also the Fahrenheit temperature plus 459.67 degrees. -459.67°F = 0 R
41.2 Fahrenheit degrees is: Celsius Scale : 5.11 Kelvin Scale : 278.26 Rankine Scale : 500.87 Réaumur Scale: 6.39 Rømer Scale : 10.18 Delisle Scale: 142.33 Newton Scale : 15.49
Some scales used for measuring temperature: Thermodynamic (absolute): Lord Kelvin Celsius: Anders Celsius (Swedish Astronomer) Fahrenheit: Daniel Gabriel Fahrenheit (Dutch-German-Polish physicist) Rankine: William John MacQuorn Rankine (Scottish Physicist) Reaumur: Rene Antoine Ferchault de Reaumur (French Scientist) Romer (or Roemer): Ole Christensen Romer (Danish Astronomer). The units for the Thermodynamic and Celsius scales are the same, the Thermodynamic is an absolute scale. The units for the Fahrenheit and Rankine scales are the same, the Rankine is an absolute scale.
The most commonly used are Fahrenheit, Celsius, and Kelvin. There are also Rankine, Delisle, Newton, Réaumur, and Romer. To measure the "heat" of spicy food, the Scoville scale is used. Chuis
